• Power Supply
    Hybrid Power Supply System for Base Transceiver Station (BTS) at Me Island, Thanh Hoa Province

    Vietnam has installed more than 64.000 BTSs so far. Each station consumes about 30KWh a day, for 64.000 BTSs the overall consumption adds up to 1.920MWh per day.

    This is aggravated by the fact that remote areas and islands are not connected to the grid.

    Thus operators of BTSs have no other choice but using diesel generators, which are more expensive and polluting.





    Given this circumstance, EDEC signed a contract with University of Technology of Ho Chi Minh City to design a Hybrid Wind/Solar/Diesel solution in January 2011.

    EDEC installed its pilot project on Dao Me island in Thanh Hoa province.

    The contribution ratio between renewable energy and diesel is expected to be 70% and 30%, respectively. Presently, there are about 6000 BTSs still running with Diesel generator. If this solution proves itself as an alternative way for BTS power supply, we can expect to save up to 126 MWh/day or 19,775 tons of CO2 per year.


  • ESCO Business Model
    Experimental Manufacturing collective – scale solar hot water systems






    The project is part of the Environmental Industry Development Program for Viet Nam. EDEC and SolarBK cooperated and installed solar hot water systems in businesses and factories.

    The installed systems help entities to save money on their electric bills. Furthermore, companies involve themselves in the energy transition and thereby improve their brand value to customers.

    EDEC calculates to what amount solar energy contributes to the total amount of required energy.
    The amount of absorbed solar energy peaks in April, when the sun satisfies the demand for energy to 88%.
    EDEC estimated that the yearly radiation provides 59% of the energy needed. Accurate numbers show that the average annual energy saving is 65%, which is above our expectations
    .



    Furthermore EDEC utilizes heat pumps as backup system. These heat pumps have a COP* of 3.8 which help to reduce the amount of additionally required energy from 35% to 10%. Solar hot water systems combined with heat pumps save 90% of energy.

    (*The coefficient of performance or COP of a 
    heat pump is a ratio of heating or cooling provided to electrical energy consumed. COP of 3.8 means that the input of 1 KW generates an output of 3.8 KW.)


     

  • R&D Innovation
    Research and apply technology to filter salt and brackish water to domestic water by using wind and solar energy


    EDEC’s R&D department has launched a new project. The project itself is part of the Environmental Industry Development Program of Viet Nam. The program will be completed in 2015 but their applications can be used until 2025.

    The project’s objective is to design, integrate and install water processing systems, which produce up to 250liters of potable water per day. The system is able to function independently, thus without connection to the grid. A hybrid power system in combination with solar panels and wind turbines make this possible. This particular form of water supply is, in case of an emergency, very helpful for people in remote areas.

    EDEC favorably received this order from the Ministry of Industry and Trade (MOIT). In August 2014, EDEC reported about the project’s 1st stage of implementation.

  • Climate Change & Environment
    Pre–FS on Gas recovery and waste treatment on Khanh Son Landfill

    Da Nang, 2012-2013,  in coordination with Department of Science & Technology

    Municipal waste poses a growing problem in Viet Nam. This particular form of waste generates tremendous amounts of methane emission and consequently amplifies global climate change.

     


    Landfills are a threat to the environment – but also a great opportunity.
    Given that all landfills generate methane, it makes sense to use the gas for the beneficial purpose of energy generation instead of emitting it to the atmosphere. Producing energy instead of harming the environment is a win-win situation for the environment and the economy.Therefore, the Ministry of Industry and Trade targets in its National Energy Efficiency Program to expand the use of landfills to produce energy.

    In April 2012, the Embassy of Denmark awarded EDEC to be the team leader for conducting a feasibility study on ‘turning organic waste into valuable biogas’ at Khanh Son landfill in Da Nang.

    OBJECTIVES OF THE PROJECT

    1. Carry out a pre-feasibility study and conceptual design for a solid waste to electricity system includes technology assessment, equipment list and general specifications.

    2. Undertake detailed economic and financial evaluations to serve as a basis for the investment decision to construct the solid waste to electricity plant.

    3. Assess and quantify all benefits arising from the process of converting waste to electricity. Benefits may be included in the financial and economic evaluation of the project.

  • Capacity Building
    ENHANCE AWARENESS FOR HOTELS STAFF ON CLIMATE CHANGE AND ENERGY SAVING ISSUES

    The tourism sector is generally ahead of other businesses in terms of environmental and green practices. The purpose may be to educate the traveler or to directly benefit the economic development of local communities.

    The tourism industry contributes upward of 6 percent annually to Viet Nam's total GDP during the last decade[Vietnam Briefing], thus the industry directly impacts the environment and the amount of energy consumption. The size of this sector shows how significant energy-saving potential is. Many hotels implemented energy saving policies – and now training their staff in this field has become a main concern as well.

     

    The Viet Nam Hotel Association (VHA) – established in 2010 with more than 200 members – decided in May 2012 to take a big step forward by promoting capacity opportunities for their members.


    VHA trusts the Energy Development Center on designing capacity building programs adapted to their specific audience:

    -          Management staff 
    -          Technical staff
    -          General staff


    on topics covering:

    -          Climate change in Vietnam
    -          Solar Energy solutions
    -          Introduction to Green Hotel concept
    -          Introduction to Clean Energy and Renewable Energy in Vietnam
